What I hate is when police officers feel the need to "teach" someone a lesson. If you were wrong, either just give you a ticket and leave or verbally reprimand you and then leave. It is the judge's responsibility to teach you a lesson, not the police officer. Although I didn't like it that he didn't explain to you immediately as to why he pulled you over, I don't believe that what he did warrants a complaint. You being nervous about police brutality that never happened does not mean what he did warrants a complaint. By your admission, he didn't yell, just asked you the same question over and over again. The streets are not the place to adjudicate a ticket, the courts are. This complaint, I promise you, will be ignored, unless you can show that A. Unnecessary force was used... (Think Rodney King) B. Abuse of Authority (Pulled you over for no reason. He apparently had one, true or not) C. He was discourteous (Called you "Girlfriend" as opposed to Ma'am or Miss.) D. He use obscene language (Used curse words) From what you have said, you can always file a complaint, but what you have stated here does not fall into any of the above categories unless you left something out that I'm missing.
